To allwhom itmay concem: I

Be it known that I, MILFORD T. VANDER- vooRT, a citizen of the United States of America, residing t Grand Rapids, in the county of Kent and-State of Michigan, have.

invented certain new and useful Improve merits in Fuel-Passage Locks forIhternal Combustion Engines; and I do hereby de- ,clare the following to be a full, clear, and

exact description of the invention, such as will enable others'skilled in the art to which it appertains to makeand use the same.

This invention relates'to a fuel passage lock for use with internal combustion eI1- gines. It is a primary object and purpose of the present invention to provide a movable lockinggate which may be operated across and close the passage for fuehbetween the carburetor and en ine, said 7' ate 2-, r

when in operative position stopping any passage of fuel to the englne, thereby 'r'endering operation of the engine impossible. A further object of the invention is to provide operationmeans for said locking gate which may be actuated to either move the gate to operative fuel obstructing position,

for operating the locking gate, similar in' operation to a combination "lock'which is manually turned back and forth to different positions, being guided as to the amount to be turned in different directions by a numbered dial similar to and operatedlike the dial in combination locks, andoperable at a distance from the fuel passage locking gate whereby, for motor vehicle'use, the dial opcrating means may be' mounted on the dash of the vehicle and operated from the front compartment thereof. Various other objects andpurposes than those enumerated,

all tending to simplicity Of'COIlS'CIllGtlOII and economy in manufacture, will appear as understanding of the invention is had from the following description, taken in connection with the accompanying drawings, in which, j Fig. 1 is an elevation showing my inven-' tion applied to the fuel conduit of an internal combustion engine.

Said casing portions?) and 4 have laterally jproto aline' with similar openings in similar ears at the endsof' partsl and 2, bolts 6' i passing through the alined openings for fixedly securing: the carburetor outlet 1, manifold end?! and parts 3 and 4 together. Said casing parts 3an'd'4'haveopenings therethrough matching the passage through I the manifold so that fuel-can passfreely fr m the carburetor to the engine when the passage therefor is unobstructed;

Extending downwardly from each part3 and f and integrally formed therewith "are frames 7 and'8 fromi'which outwardly projecting semi-cylindrital housings extend; in

opposite directions as indicated at 9 and 10.7

100. A hollow and short cylindrica-l'housing'is made through which a shortfhorizontal shaft 11 extends, being rotatably mounted v at its ends in bearings 12 and 13 as shown in Fig.

A flexible shaft 14,. housedwitliin atube 15 is connected at one end to shaft 11,1eading atitsfother' end. to the dash 16 and through the same; A eircular 'plate 17 is: connected to the rearside'of the dash over f whichadial 18 is placed, the same having a i knob '19 through whieha set screw 20 passes to o'o'riiieet'the diallto a short shaft or pin 21 which is permanently connected to the other end of the flexible shaft 14. By turning the dial hack and forth the shaft 11 may like eaehfside iof th member; said ceinlni'eihherajdlsk relocated, loose Wise be turned back and forth as is obvious.

A cam member 22 is 'e'onneeted to and turns with the shaft 11 within the hollow housing, being or the shape shown inf 'Fi 5 andTG and havingai rcj'ecfing tongue 23 at ,o'iies'ide had a 'pin 24'pa'ssing there through andextending a short distane to on the..shaft lfand haiiing a Circular slot cut therein which extends nearly through the feiitire are of thedisk and 'with'a radial "slot" out inwardly in'the' disk between the enil'siofkthe oirularjsiot 'Thefradial slot is 'hbii fi at 26"aiid 'the cireuiar'slet' zit-'27." v
